One of my galleries is asking for barrettes for the holidays and i'll probably do a few dozen for some walking-around money. It's not the most interesting thing to do, but i got to thinking that they depend on folks like me who have a cheap production item to offer as stocking stuffers, and they cost me nearly nothing to make out of my endless boxes of lazy-susan corners. As you said, "printing money", and it may be worth considering as an item for you to make in the post-Christmas season. I can make about four times as much per hour doing barrettes as making custom furniture, sad but true.
I used to sell lots of jewelry boxes in the $100-$125 range through that gallery, but i'm still not settled in the shop enough to do a production run of 30 or 40 to make it worthwhile. Maybe next summer, for the tourist season...but then the hoophouse[s] will be up and running, and...<G>
